Whether it is through stainless steel deburring equipment or cutting deburring or rotary removal of burrs, the Angle of the knife is an important factor affecting the removal of burrs. According to the structural characteristics of the burr machine planned in this paper, selecting the appropriate cylinder pressure is also one of the main factors to determine the burr removal effect.
1, tool Angle
The front burr of the casting blank is shot down by rotating the cutter head at high speed. The four blades are centered on the axis of rotation and evenly arranged around them, but the direction of the blade is angled to the center line of the axis of rotation. Deburring machine
The burrs at the back end of the billet are scraped off by the flat scraper of the stainless steel deburring equipment. In order to adapt to the deformation of the abdomen of the billet, the placement of two flat blades is tilted to the center, the horizontal line is a certain Angle α, and the micro-V-shape can maintain the surface of the billet from damage, and it is useful to remove burr.

2, cylinder pressure
According to the process flow of the combined billet burring machine, when the equipment is in the standby position, the cylinder shaft is perpendicular to the ground, and the stroke reaches the Z value, the structure should adhere to the horizontal. The stainless steel deburring equipment can calculate the thrust standard required by the cylinder through the torque balance formula, and then calculate the pressure standard required by the cylinder according to the cross-sectional area of the piston. Automatic deburring machine
The on-line burr removal method for continuous casting of large blank takes into account the different orientation of the burr at the front and back of the casting blank. Combined with the burr scraping and rotary removal methods, the casting blank separates the front and back ends of the casting blank during transportation, which has a prominent burr removal effect. When removing burrs, there is no need to suspend the casting blank, the equipment is simple in structure, small in size, easy to maintain, and can be easily set between the two rollers of the roller table, without affecting the placement of other equipment and the rhythm of billet production. The equipment has been applied to continuous billet casting line of Shaogang Dafang, and obtained excellent function of stainless steel burr removal equipment.
